药用真菌是具有保健和治疗疾病作用的一类真菌,能产生丰富的次级代谢产物。多糖是一种重要的次级代谢产物,具有抗肿瘤、降血脂、抗病毒等多种生物学活性,目前已成为一个研究热点。从培养基成分角度,综述碳源、氮源、碳氮比、无机盐、生长促进物质、植物油、真菌激发子对药用真菌多糖产生的影响。 Medicinal fungi are a group of fungi that have a role in the care and treatment of diseases and produce abundant secondary metabolites. Polysaccharides, as an important secondary metabolite, have many biological activities such as anti-tumor, anti-hyperlipidemia and antiviral activity and so far have become a hot research topic. The effects of carbon sources, nitrogen sources, C / N ratio, inorganic salts, growth promoting substances, vegetable oils and fungal excitons on the polysaccharides of medicinal fungi were reviewed from the aspects of medium composition.
